Find the Domain -3y+7x=-28

Problem

−3*y+7*x=−28

Solution

1. Identify the type of equation. The equation −3*y+7*x=−28 is a linear equation in two variables.

2. Solve for y to express the equation in slope-intercept form.

−3*y=−7*x−28

y=7/3*x+28/3

3. Analyze the resulting function. The function ƒ(x)=7/3*x+28/3 is a polynomial function of degree 1.

4. Determine the domain. Since there are no square roots of negative numbers, no logarithms of non-positive numbers, and no denominators that can be zero, the function is defined for all real numbers.

Final Answer

Domain: *(−∞,∞)
